Many patients are treated for advanced cancer without knowledge of underlying molecular features that might indicate FDA approved therapies or potential eligibility for biomarker-selected clinical trials. Strata Oncology is initiating the Strata Trial (STR-001-001) with the primary goal of understanding the proportion of subjects available for clinical trials and approved targeted therapies in advanced cancer while assessing the feasibility of using a large-scale NGS screening program to match subjects for eligibility assessments in clinical trials and/or for approved targeted therapies. The Strata Trial does not require additional procedures but rather uses surplus, or leftover tumor specimens for molecular profiling.
